Drive Faults; Automatic Fault Reset; Manual Fault Reset - ABB ACL30 User Manual

Drive faults

Drive faults are considered as critical and non-critical faults. See chapter
on page 289.
• critical faults trip the drive immediately, drive stops modulation and closes the
brake.
• non-critical faults allow the drive to continue modulation until start command is
removed, that is the elevator continues travel to the destination floor and drive
trips when it is stopped.


Automatic fault reset

The Automatic fault reset function resets pre-defined drive faults to ensure the
operation of the drive in temporary fault situations.
When any one of the selected faults occur, a trial time defined with parameter
AUTORST TRL TIME starts and a fault reset is generated. You can define the
number of resets to be generated within the trial time with parameter
AUTORESET TRIALS. With parameter
define for how long the drive waits after a fault before attempting a fault reset.
